Soft magnetic alloys

Osprey® Fe8Cr

Osprey® Fe8Cr is a ferritic soft-magnetic steel with superior corrosion resistance to that of low-alloy steel and SiFe binary alloys. It is typically used in automotive applications.

This metal powder is manufactured by Inert Gas Atomization (IGA), producing a powder with a spherical morphology which provides good flow characteristics and high packing density.
